The Brief & Expansive History (And Future) Of The Mooc: Why Two Divergent Models Share The Same Name, Rolin Moe

Current Issues in Emerging eLearning

Within popular media, the massive open online course (MOOC) is presented as a novel idea created by maverick professors and further developed with a goal to further democratize education on bases of quality and cost. The perception of this sequence of events as modular history has perpetuated a difficulty in developing MOOC-related research and critique within the fields of distance and online education. At the center of this struggle is the MOOC acronym: its initial development was in 2008, and its use today happens in opposition to the theoretical and pedagogical elements of the 2008 MOOC. This paper endeavors to …

The Dark Side Of The Mooc - A Critical Inquiry On Their Claims And Realities, Markus Deimann

Current Issues in Emerging eLearning

Building on the work of French philosopher Michel Foucault, this paper utilises critical discourse analysis to examine claims attached to MOOCs in New York Times articles published between 2012 and 2013. Discourse analysis is proposed as a valuable tool enabling the understanding of MOOCs as historically constituted and socially constructed “events” with hidden meanings masked by rhetoric slogans. Noting that language is not just the reflection of social and psychological life but rather constructs social realities, this work posits how both media and commercial MOOC providers have constructed an “education is broken” narrative which states (1) traditional universities are no …

Down The Rabbit Hole: An Initial Typology Of Issues Around The Development Of Moocs, Apostolos Koutropoulos, Panagiotis Zaharias

Current Issues in Emerging eLearning

MOOCs have experienced an unprecedented explosion of publicity. This publicity indicates both optimism that they may be the panacea for whatever ails higher education, as well as caution and trepidation that this may in-fact be some sort of new fad in higher education. In this wave of optimism, and subsequent wave of pessimism, we believe that there is something good to examine about MOOCs and that they do hold potential for certain educational arenas. That said, we don’t want to blindly dive into the MOOC optimism camp. We have critically examined the literature, from both academic peer-reviewed and academic press …

Microstructure And Geotechnical Properties Of St. Peter Sandstone In Clayton, Iowa, Amir Hossein Bagherieh

Doctoral Dissertations

"The St. Peter Sandstone is significantly different from the minerals and rocks which have been studied extensively in mining. It is brittle and characterized by an unusually high friction angle. On the other hand it is friable, and it is nearly cohesionless. The scarcity of the ground control techniques for this particular mining environment has created many difficulties for mine operators. This research aims to establish a fundamental understanding of the basic mechanical and strength properties of the St. Peter Sandstone for engineering design and scientific research. The specific objectives are 1) characterizing the strength of the St. Peter Sandstone, …

Numerical Study Of Upstream And Downstream Regions Of One Dimensional Detonation Wave In A Dusty Gas Medium, Shubhadeep Banik

Masters Theses

"In detonative combustion very high temperatures are attained by the burned gases. As a result, a large amount of thermal energy is produced during the combustion process. This heat can affect the state of the unburned fuel through radiation of heat from the burned gases. In this study a one-dimensional model was deemed appropriate to gain insight into the fundamental structure of the detonation wave. In this model, the detonation wave divides the fluid stream into an upstream region, consisting of fuel and oxidant, and a downstream region, consisting of burned gases. A set of computer programs, some developed during …

Palynological Interpretations Of Deep Sea Drilling Projects Cores In The Gulf Of Mexico And Bahamian Platform, Adam Patrick Barron

Masters Theses

"One hundred drill core samples were from Deep Sea Drilling Project (DSDP) Sites 94, 98, and 540 were investigated for their palynological contents (pollen, spores, acritarchs, dinoflagellate cysts, and dispersed organic matter) to infer the paleoenvironmental and paleoceanographic history of the Gulf of Mexico and the Bahamian Platform during the middle Eocene to middle Miocene interval. At Sites 94 and 540, abundant dinoflagellate cysts (chiefly Operculodinium centrocarpum, Lingulodinium machaerophorum, Impagidinium sp., Nematosphaeropsis sp., and Spiniferites spp.) were used as paleoenvironmental indicators. Two alternating palynofacies assemblages were identified from dispersed organic matter analysis: terrestrially influenced assemblage A and marine dominated assemblage …

Evaluation Of Preformed Particle Gel Treatment Using Homogeneous And Heterogeneous Models, Hilary Ogochukwu Elue

Masters Theses

"This research investigates the effects of preformed particle gel (PPG) in remedying the problems of excess water production and low oil recovery of heterogeneous reservoirs by placing the PPG in the high-permeability layer, thus diverting displacing brine to the unswept low permeability layer. This investigation was completed with three tasks.

The first task was to evaluate the PPG swelling kinetics and strength as a function of concentration of brine. The result of this task indicate that PPG prepared with low concentration of brine swells more, becomes weaker, more deformable than PPG prepared with high concentration of brine.

The second task …

Thermodynamic And Chemical Kinetic Coupled Modeling For The Determination Of Cyclic Combustion Phasing In Hcci Engines, Krishawn Michele Goodwin

Masters Theses

"Homogeneous charge compression ignition (HCCI) is a low temperature combustion mode that contains great potential for decreasing emissions while increasing efficiency in internal combustion engines. The limitation is in that it is inherently difficult to control based on the lack of an external combustion trigger. This thesis outlines the potential of using the combustion residual species of carbon monoxide as a method of controlling the location of combustion by using data from a computer model. The model is a nonlinear five-state thermodynamic model that is coupled with a skeletal chemical kinetic model for PRF96. The model computes the amount of …

A Subband Kalman Filter For Echo Cancellation, Rakesh Vijayakumar

Masters Theses

"This thesis involves the implementation of a Kalman filter for the application of echo cancellation. This particular Kalman filter is implemented in the frequency domain, in subbands, so as to make it faster and of lesser calculational complexity for real time applications. To evaluate the functioning of this subband Kalman filter, comparison of the performance of the subband Kalman filter is done with respect to the original time domain Kalman filter, and also with other subband adaptive filters for echo cancellation such as the NLMS filter. Additionally, since background noise affects the working of any adaptive filter, the newly developed …

Where Have We Been And Where Are We Going? A Conceptual Framework For Child Advocacy, Michele Cascardi, Cathy Brown, Svetlana Shpiegel, Ariel Alvarez

Department of Social Work and Child Advocacy Faculty Scholarship and Creative Works

The primary goal of this article is to chart the development of child advocacy as an interdisciplinary field of study and conclude with a conceptual framework for research and higher education in child advocacy. Historically, child advocacy has justifiably focused on protection needs. Values and assumptions about children's best interest have also governed child advocacy, in part because evidence to inform decisions was lacking and in part because of its history as an activist movement. Against this historical backdrop, we describe contemporary trends in child advocacy that reconcile children's protection with their inherent rights to personhood. We rely on the …

Youth Activism, Art And Transitional Justice: Emerging Spaces Of Memory After The Jasmine Revolution, Arnaud Kurze

Department of Justice Studies Faculty Scholarship and Creative Works

This chapter explores the creation of alternative transitional justice spaces in post-conflict contexts, particularly concentrating on the role of art and the impact of social movements to address human rights abuses. Drawing from post-authoritarian Tunisia, it scrutinizes the work of contemporary youth activists and artists to deal with the past and foster sociopolitical change. Although these vanguard protesters provoked the overthrow of President Zine El Abdine Ben Ali in 2011, the power vacuum was quickly filled by old elites. The exclusion of young revolutionaries from political decision-making led to unprecedented forms of mobilization to account for repression and injustice under …

Hofstra Law Review

The article discusses America's probable cause legal doctrine, the Fourth Amendment to the U.S. Constitution, and the reasons why the U.S. Supreme Court should establish a bright line rule for law enforcement regarding requests for cell towerdumps which encompass all of the cellular transmissions and calls that are transmitted through a cell tower at a given time. According to the article, a specific facts standards should be required in order to law enforcement to obtain cell towerdumps.

Keep Securities Reform Moving: Eliminate The Sec's Integration Doctrine, Stuart R. Cohn

Hofstra Law Review

Small and developing companies raising capital under the federal securities laws often face the considerable barrier imposed by the SEC's integration doctrine. Despite recent reforms in registration exemptions the integration doctrine has remained untouched and continues to be a significant problem for many companies needing multiple infusions of capital. This article examines and recommends that the integration doctrine be eliminated nearly in its entirety.

The Curious Exclusion Of Corporations From The Privileges And Immunites Clause Of Article Iv, Stewart Jay

Hofstra Law Review

Since the mid-nineteenth century, courts consistently have held that corporations cannot be citizens for purposes of the Privileges and Immunities Clause of Article I of the U.S. Constitution. Judges reasoned that because corporations were not humans, they were unable to be “citizens” eligible for the clause’s protection against discriminatory treatment by states. Yet the Supreme Court also held that corporations were citizens for purposes of federal judicial jurisdiction, as well as “persons” under the Fourteenth Amendment. Extending these constitutional protections to corporations is based on the idea that businesses are owned by actual people who are harmed when their companies …

Stop Blaming The Prosecutors: The Real Causes Of Wrongful Convictions And Rightful Exonerations, Charles E. Maclean, James Berles, Adam Lamparello

Hofstra Law Review

Wrongfully convicted and rightfully exonerated criminal defendants spent, on average, ten years in prison before exoneration, and the ramifications to the defendants, the criminal justice system, and society are immeasurable. Prosecutorial misconduct, however, is not the primary cause of wrongful convictions. To begin with, although more than twenty million new adult criminal cases are opened in state and federal courts each year throughout the United States, there have been only 1,281 total exonerations over the last twenty-five years. In only six percentof those cases was prosecutorial misconduct the predominant factor resulting in those wrongful convictions. Of course, although prosecutorial misconduct …

Republicanism: Philosophical Aspects, Mortimer N.S. Sellers

All Faculty Scholarship

Republicanism is the doctrine that public power should always serve the common good of all those subject to its rule. This raises the question how to do so most effectively, either through particular policies or through constitutional structure (‘the republican form of government'). The republican philosophical tradition began with Plato and Aristotle, flowered in the writings of Marcus Tullius Cicero, and reappeared with the revival of learning in such authors as Niccolo Machiavelli, James Harrington, John Adams, and Immanuel Kant. More recently Philip Peuit, Jürgen Habermas, and others have returned to the republican conception of liberty as nondomination, and how …
